1. An apparatus for measuring the length and width of a linearly-moving object having a rectangular boundary traveling at a determinable rate along a predetermined path, comprising:

  • beam emitters for emitting first, second, third and fourth light beams across said path of said linearly-moving object so as to be interrupted by the passage thereof, each of said beam emitters being oriented to emit beams so that each of said beams is in non-parallel orientation to each of the other three beams;

    a timing mechanism for determining first, second, third and fourth times during which each of said respective first, second, third and fourth light beams is interrupted by the passage of said object;

    a speed sensing mechanism for determining magnitude of said rate; and

    a processor for calculating said length and said width of said rectangular object using said determined first, second, third and fourth times and a determined magnitude of said rate.
